divided into a number of smaller blocks orv pieces by the aid of an `ordinary ice pick or l other suitable tool.

The object of the invention is to provide a simple and efhcient method and means which' can be applied to an ordinary ice house plat-v form and willich will act upon the ice while the block or cake is in motion; and with these objects in view the invention consists in providing a movable carrier for elevating er block or cake of ice, arranging horizontal saws upon opposite sides of said 'ele-y vator, so that the cake is scored horizontally on opposite sides as it moves along` arranging a cage in a chute at the end of said elevator w'hich cage is caused to descend by the weight of the block or cake held therein and bring.'y said block or`cake into contact with a series of vertical saws by means of which the block or cake is scored vertically at definite points as the cage descends to the bottom of the chute, where the block or cake is automatically discharged upon the platform, ready tor delivery to a sales wagon.

The invention consists also in certain details hereinafter fully described and pointed out in the'appended claims.

inthe drawings forming a part ot' this specification Fig. 1 is a side elevation partly' in section of one form of the apparatus de signed for carrying my invention into `eitect. Fig. 2 is a plan view of the same (with the dash pot or control being omitted), Fig. 3 is a detail view of the cage and saws arranged in the chute, and Fig. 4 is a per spective view of a block of ice after scoring.

Various forms of devices may be employed for carrying my invention into effect and in the drawings I have shown one form in which 10 indicates an endless conveyor or of which a block or cake of ice 11 can be lelevated from the platform 12 and delivered to a cage 13 which works up and down in a chute 145 there being a suitable guide or shelf l5 interposed between the endf of thel elevator and thechute to direct the block or cake of ice to the cage, there being an open-l ing 16 in the side of the chute largeenough to receive the cake of ice.

Suitable carrying saws or disks 17 are are y ranged parallel with the elevator, above the same and'on opposite sides thereof said saws overhanglng eelevator so that as the cake of ice 1s carried along by said elevator the sides of said cake are scored horizontally as the cake passes between the saws. The saws are mounted upon the upper ends ofi shafts journaled in suitable frames 18 rotatedI from any suitable source. -lVhen the cake of ice reaches the top of the elevator it is de-- livered lx) the inclined guide orshelf l5 and slides through the opening 14a of the chute 14'and is scored in the cage 13 which is held suspended in the chute by means of a cable 19 passing around the sheaves 20 and 21 to a' weight 22 which works in the cylinder 23 filled with oil or water, the weight having suitable passageways through which the' oil or water can pass as the weight is raised or lowered. The weight is' sul'licient to hold the cage in its raised position but when the cake of ice is placed in said cage the weight of the cake is suiicient to raise the weight 22 and cause the cage to descend. The cage is made of channelior angle iron and 'is so constructed that thehides of the cakes of ice will be exposed to the .vertical saws 24 mounted uponthe shafts 25 journaled in the, chute, said shafts beingr inclined. so that as the cage travels down the chute which is preferably inclined,` the sides oiithe cake will be scored vertically, the shafts uponl which the saws are mounted being driven from any suitable source. When the cage reaches the bottom of the chute the cake ot ice is discharged through the door la onto the skid 26 down which it slides'to the plat form 27. By inclining the elevator 10 and imparting tilt or inclination to the chute I14;-

I' am able to perform the scoring operations vertical land in this event the shaft would be horizontal instead of slightly inclined es shown. The cage 13 is provided with suit- 'les guides 13a which engage the rails 'i.3

arranged upon the inierier ef the chute. if'y scoring e cake 'of ice horizentiiiy and ven ticaiiy upen Opposite sides die iimits er boundaries of he smeiier cakes er blocks are cieariy defined and by the use of an ordinary ice pick or ether simiiar mei, the iargge cake or bleek can be quickly and easily divided vinte e number of smaiier biecks or mires.

This insures accuracy ei' measurement in the sale oi' ice end in cese the purchaser shenid piirciiase any ammini'. in excess ci' the smaiies; sized biock, the intermediate merk would serve as en indicaing notice ci iii@ accuracy of ihe weight. @ther edvei'ieges of the method ind zipper-eins wouid be e1;- lparent to everyone skiiied in the art te which ibis invention reietes.
